Problems solved by technology

[0003] However, during the research process, it was found that due to the large molecular weight and entanglement between molecular chains, UHMWPE has high molecular viscosity and complicated processing. Especially when used as a fiber in the textile field, the spinnability of the fiber stock solution has become the most important problem to be solved.
At this stage, people often use the form of adding additives to enhance the fluidity and processing performance of UHMWPE, but while improving the fluidity of UHMWPE, its own excellent performance is reduced.

[0043] The preparation method of dopamine-modified carbon nanotubes refers to the following steps:

[0044] (1) Weigh 30-80 mg of carbon nanotubes in a three-necked flask, add concentrated sulfuric acid with a mass fraction of 98% and concentrated nitric acid with a mass fraction of 67% into the three-necked flask, the volume ratio of the two is 3:1, and ultrasonically disperse 60-90 minutes, at 60°C, condensing and refluxing for 2-4 hours, then lowering the temperature of the obtained reactants, washing to neutrality, and drying the obtained modified carbon nanotubes for later use;

[0045] (2) Take 40 mg of modified carbon nanotubes and 80 mg of dopamine obtained in step (1), add them to 100 ml of distilled water, and disperse in an ice-water bath at 0° C. for 10-15 minutes;

[0046] (3) Place the modified carbon nanotubes dispersed in step (2) at 20-30° C., react for 24 hours, filter and dry to obtain dopamine-modified carbon nanotubes.

Description

technical field [0001] The invention belongs to the field of fiber technology, and more specifically relates to an antibacterial and antiviral UHMWPE functional fiber and a preparation method thereof. Background technique [0002] Ultra-high molecular weight polyethylene (UHMWPE) is used as a fiber in the textile field because of its super wear resistance, chemical stability, high strength, and self-lubricating properties brought about by its linear polymer structure. The fabric becomes the research direction that researchers are interested in. [0003] However, during the research process, it was found that due to the large molecular weight and entanglement between molecular chains, UHMWPE has high molecular viscosity and complicated processing. Especially when it is used as a fiber in the textile field, the spinnability of the fiber stock solution has become the most important problem to be solved. At this stage, people often use the form of adding additives to enhance th...
